Guest MAC address isn't getting sent via Airport connection?

Hi

I'm evaluating PD (5.0.9344) for running an Elastix machine (based on Red Hat Linux), connected to the network via Airport.

It is crucial for the virtual machine to have a fixed IP inside the LAN in order for various services to function properly. Also, it must have a different IP than the host machine which is something that happened automatically once I chose Airport "Bridged Networking" for the guest.

My router allows reserving IPs based on MAC addresses, but even though I made sure to *uncheck* the box "Send the host's MAC address to the DHCP server" the router still sees the guest machine with the same MAC address as the host.

Is this a bug in PD? Am I missing something here? Any known workarounds?

Thanks!

Hi,

afaik most of the linuxes don't send to DHCP-server the so-called "DHCP-Client-ID". According to internet-standard, DHCP-server should give the IP based on this ID and only when client doesn't send it, dhcp-server uses Mac Address. You need to try to configure the dhcp-client in Linux to send it.

Take a look at http://download.parallels.com/desktop/v5/docs/en/Parallels_Desktop_Users_Guide/28189.htm

If RedHat distribution uses dhclient.conf, check that this conf-file has lines

interface "eth0" {
send dhcp-client-identifier 1:00:1C:42:xx:xx:xx;
}
where 00:1C:42:xx:xx:xx - is Mac Address of VM.

No, this is proper behaviour, WiFi doesn't pass anything else
 
I followed your instructions (the dhclient.conf file didn't exists at the location of "strings /sbin/dhclient | grep etc | grep dhclient.conf", but I created it there).

After rebooting the machine I still see the exact same MAC address belonging to the host in the router entry for the guest.

Any ideas?

No, this will not work, because it is required to modify exactly the config file of dhcp-client of your linux.

Try to search the web to get what is the dhcp client in your linux distribution or ask how to configure the dhcp-client on forums of Elastix

btw, don't you want to configure just a static IP-address?
